Calculate the density of the sample in Kg/L:

Sagot :

Answer:

Density of the sample in Kg/L is 8kg/L.

Explanation:

we know that density of a substance can be calculated if we know the mass and volume of the substance.

In this case mass, (M) = 320 g

and Volume (V) = 40 ml

we know that density (ρ) = [tex]\frac{Mass}{Volume}[/tex] = [tex]\frac{320}{40}[/tex] g/ml = 8 g/ml

We also know that 1kg = 1000g and 1litre = 1000ml

so to convert g/ml to kg/l

ρ = (8 × [tex]\frac{1000}{1000} \fra[/tex] )Kg/L = 8 Kg/L
